@skinzy Over at SoundStageNetwork.com | SoundStage.com - SoundStage! Home the former reviewer there, Jeff Fritz, wrote several articles about vintage amps and how good they sounded to him. It was in his series on his amp search, his current reference amp was a $25k-ish used Boulder amp, and I think it was a Theshold or Coda amp that he used temporarily that made him wonder about the very expensive amps he was always reaching for.
Saying all of that, my most expensive electronic piece is my amp. I also hope to buy another brand-new amp for 2x the price of the used amp. It is not better than what I have but it sounds different. Variety.
BTW - I always like Classe amps.
